GLAZING TOOLS Filed Oct. 6, 1951 Dm l'frl' Vai/ INVENTOR ATTORNEYSUnited States Patent This invention relates to new and usefulimprovements in glazing tools.

One object of the invention is to provide an improved glazing tool orputty knife which is so constructed that excess putty may be removedfrom a glass pane simultaneously with the application of and smoothingof the putty.

Another object of the invention is to provide an improved glazing toolor implement having a pair of blades disposed in angular relationshipand having their Work engaging edges angularly disposed for coaction toapply and smooth glazing material and remove excess material from aWindowpane in one continuous operation.

A particular object of the invention is to provide an improved glazingtool, of the character described, which includes a glazing blade havingan edge for applying and smoothing putty and an auxiliary blade havingan edge disposed in angular relation and close proximity to the glazingblade and its edge for engaging a windowpane to remove excess puttytherefrom, said glazing blade having a projecting portion adjacent theauxiliary blade edge to facilitate use of the tool in the corners ofwindowpanes.

An important object of the invention is to' provide an improved tool, ofthe character described, wherein the glazing blade has an edge forbearing against the Window pane and cutting the putty, the cutting edgebeing formed on the projecting portion of said blade substantiallybetween its smoothing edge and the edge of the auxiliary blade wherebythe putty may be smoothed and cut in a substantially straight=linemovement in the corners as well as along the margins of the windowpane.

A further object of the invention is to provide an improved tool, of thecharacter described, wherein the edge of the auxiliary bladesubstantially intersects the cutting edge of the glazing blade forcoacting therewith in removing excess putty from the windowpane.

A construction designed to carry out the invention will be hereinafterdescribed together with other features of the invention.

The invention will be more readily understoodfrom a reading of thefollowing specification and by reference to the accompanying drawing,wherein examples of the invention are shown, and wherein:

Fig. l is a perspective view of a glazing tool constructed in accordancewith the invention and showing its: relation to the lower corner of awindow frame and its glass pane,

Fig. 2 is a perspective view of one end of the tool showing its relationto" the upper corner of a window frame and its pane,

Fig. 3 is an underside plan view of oneend of the tool,

Fig. 4 is a transverse, sectional view of the tool, taken on the line4-4 of Fig. 2,

Fig. 5 is a perspective view of one end of the glazing blade of the toolwith the auxiliary blade removed, and

Fig. 6 is an underside plan view of a portion of one end of the tool,showing a slight modification.

In the drawing, the numeral 1i} designates an implement or tool forglazing a conventional glass Windowpane 11 in the frame 12 of a sash,door or other closure. The tool 19 is in the form of a knife andincludes a fiat, thin, glazing blade or member 13 which may be formed ofmetal, plastic or other suitable material. Although the form of the toolis subject to variation, it is desirable to provide one of the blades 13at each end of said tool and connect said blades by an intermediatehandle portion M whereby the tool is double-ended or reversible. Use ofthe tool is facilitated by disposing the blades at an angle to thehandle portion 14, but such angular relationship is not essential. Theblades are preferably coplanar with the handle portion and project atobtuse angles from the ends, and from the same side of said handleportion. Thus, the blades extend at obtuse angles to each other andoccupy opposed or reversed positions when the tool is inverted orturned.

Each blade 13' has a transverse straight edge 15 at its outer end forapplying and smoothing putty or other glazing material 16 including thesquaring or cutting out of the putty at the corners of the pane. Quecorner, preferably the inner corner or the left-hand corner of the upperblade, is cut away or removed or bevelled or rounded to provide a corneredge 17 of relatively short length for bearing against the pane 11 tocut the putty along a line 12; of demarcation between said pane andputty. A substantially upright plate 19 is suitably secured to the uppersurface of the blade for adjustably supporting an auxiliary scrapingblade or member 20. The plate 19 extends at substantially a right angleto the corner edge 17' so as to be disposed diagonally of the blade andits edge 15. For clamping the member 20 against the plate, one or morearcuate slots or openings 21 are formed in said plate to receivefasteners, such as screws or bolts 22 extending transversely throughsaid member and having wing nuts or lugs 23 threaded thereon.

- The member 24 is substantially triangular and has a straight edge 24extending laterally and upwardly from the intermediate portion of thecorner edge 17 (Figs. 3 and 4) for contacting the pane to scrape orremove excess putty therefrom. In addition, the straight edge 24functions as a rest or guide for the glazing blade and determines theangle of the exposed surface of the putty to the pane.

Due to the provision of the slots 21, the member may be pivoted or swungoutwardly in anare relative to the blade 13 to vary the angular relationof its edge 24 to said blade and its edges 15' and 17. The memberfulcr'u'ms upon the corner edge and it may be desirable to provide ashallow groove or recess 25 in the upper surface of the member (Figs. 4and 5) parallel to and immediately adjacent the plate 1? for receivingthe lower edge of said member. By inclining the groove 25' down wardlyand outwardly to the lower margin of the corner edge, the edge engagesand extends from said lower margin. in use, the corner edge 17 bearsagainst the pane and projects ahead of the member edge 24' to initiallycontact said pane and cut the putty 16 along the line 18. The transverseedge 15 engages the putty for smoothing the same, while the edge 24extends ansverseiy of the pane with its entire length substantially incontact therewith. Since the lower blade is identical to the upper bladeexcept for the reversal of its elements, it is manifest that the tool isreversible for use on any side of a pane and in either direction.

It is noted that the glazing tool described hereinbefore represents apreferred or" desirable embodiment of said tool and is subject tovariation as shown in my co"-pending application, Serial No. 220,641,filed April 12, 1951. The tool illustrated herein includes animprovement which facilitates use of the tool in the corners ofwindowpanes as shown in Figs. 1 and 2. A substantially triangularenlargement or projection 26 is provided by laterally extending thelongitudinal margin of the blade carrying the corner edge 17, wherebysaid edge is disposed or projects laterally outward of the remainder ofsaid longitudinal margin. Thus, the remaining longitudinal margin of theblade does not contact and mar the putty 27 and 23 previously applied tothe upper and lower edges of the pane, respectively. Due to theprovision of the projection 26, the putty may be smoothed and cut in asubstantially straight-line movement in the corners as well as along themargins of the pane, whereby it is unnecessary to swing the tooloutwardly away from or change its angular relation to said pane uponapproaching said corners.

A slight modification is shown in Fig. 6, wherein the inner or lower endof the corner edge 17 is relieved by being cut away or bevelled as shownby the numeral 29. Due to the bevel 2?, the tendency of the corner edgeto drag against and pull or burr the putty along the demarcation line 18is reduced.

Theforegoing description of the invention is explanatory thereof andvarious changes in the size, shape and materials, as well as in thedetails of the illustrated construction may be made, within the scope ofthe appended claims, without departing from the spirit of the invention.
